Not sure about Jailbait, but I've got the wlan-ng usb driver working on Midori linux. See http://m4i.homeip.net/
Note that there are two versions of the Linksys WUSB11- the original and 'version 2.5'. Version 2.5 has a folding antenna, the orginal has no external antenna. Version 2.5, which has a prism chipset, is supported under linux with the wlan-ng prism driver. The original has an Atmel chip that is NOT supported under linux.
I'm using the WUSB-11 v2.5 on my Iopener under linux to post this right now- it works great!
